Question

A charge of `12 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `58 J` to `42 J`, what is the voltage between points A and B?

Answer 1

See the explanation below

Explanation:

Apply the equation

`"Energy"(J)"` `= " Electric potential(V)"xx"Charge (C)"`

The charge is `Q=12C`

The change in energy is `DeltaE=58-42=16J`

The voltage is

`U=(DeltaE)/(Q)=16/12=1.33V`
